Custom Marine Hydraulic Speed Reducer & Gearbox

About product

Our company specializes in the custom manufacturing of marine hydraulic reducers and gearboxes, widely used in shipboard power systems such as windlasses, winches, cargo hoists, and thrusters. Our replacement marine motor gearboxes serve as critical components in the ship’s power transmission chain, responsible for transferring power, adjusting speed, and amplifying torque.

  • Featuring a modular design, the speed ratio can be customized by adjusting gear parameters such as module and number of teeth. For certain models, the speed ratio range can reach 1:1 to 1:10, with torque output covering 1,000–5,000 N·m.
  • The design integrates hydraulic motors with the reduction mechanism, such as cycloidal hydraulic motors coupled with planetary gears, achieving a compact configuration suitable for space-constrained shipboard compartments.

Product Detail

Custom and Replacement Marine Hydraulic Speed Reducer & Gearboxes

We utilize self-developed molds in production to ensure the structural precision and performance stability of each gearbox and hydraulic reducer. The design fully considers high-strength load capacity, corrosion resistance, wear resistance, and space adaptability for confined shipboard compartments, ensuring reliable performance during long-term maritime operation.

Additionally, our marine hydraulic reducers and gearboxes can be customized for power, torque, speed, and installation dimensions to meet the requirements of different vessel types and operating environments. High-performance steels or alloys are selected as materials, combined with precise heat treatment processes to enhance wear resistance and service life, while surface anti-corrosion treatment ensures long-term seawater resistance.

Marine Planetary Gearbox

  • Designed for high-torque, large reduction ratio marine power applications, such as propulsion systems. Multi-stage planetary gear assemblies can achieve high reduction ratios (e.g., 1:100) with transmission efficiency exceeding 95%.
  • Typical applications include direct coupling with hydraulic motors, replacing traditional shaft-driven systems, effectively reducing energy loss and enhancing power transmission efficiency and system reliability.

Marine Cycloidal Pinwheel Reducer

  • Featuring a compact structure and low noise, ideal for auxiliary equipment on small ships. Reduction ratios range from 1:9 to 1:87, with torque output covering 200–2000 N·m.
  • The split-type design allows for easy maintenance and component replacement, extending service life and improving operational convenience.

Marine Hydraulic Gearbox Replacement Solutions

For upgrading older ship power systems, traditional gearboxes can be replaced with high-efficiency planetary gearboxes or cycloidal pinwheel reducers to improve power transmission efficiency and system reliability.

  • High Efficiency and Energy Saving: Reduces energy loss and increases transmission efficiency, reaching over 95%.

  • High Reduction Ratio Capability: Multi-stage gear design allows a wide range of speed ratios to meet various power requirements.

  • Flexible Installation: Modular design adapts to different shipboard space layouts.
